The dancer claims she was rehearsing for the pop star’s “Work Bitch” music video on August 19 when Spears showed up appearing “unbalanced” and “disheveled.”

Pignuola alleges she was standing next to Spears when the singer “twirled in the unbalanced and reckless manner, arms extended out to her sides, and forcefully backhanded” her in the face.

The dancer claims Spears apologized but rehearsal continued. Court documents state Pignuola left practice a half-hour later to receive medical care.

However, Pignuola claims Spears’ representative told her months later she would not be reimbursed.

A spokesperson for Spears had not commented on the claims at press time.

Pignuola is seeking unspecified damages.
